Explain how carbon’s electron configuration determines the kinds and number of bonds that carbon will form.
Carbon has a total of 6 electrons with 2 electrons in the first electron shell and 4 valence electrons in the
second shell. Carbon does not fill its valence shell by losing or gaining 4 electrons. Instead, it completes the
shell by sharing electrons with other atoms using four covalent bonds, this is called tetravalence. Tetravalence
allows large, complex molecules possible. The shape is of a tetrahedron with bond angles of 109.5°. When two
carbon atoms are joined by a double bond, all bonds around those carbons are in the same plane and have a
flat, three-dimensional structure.
The electron configuration of carbon makes it capable of forming covalent
bonds with many different elements.
Describe how carbon skeletons may vary, and explain how this variation contributes to the diversity and
complexity of organic molecules.
The carbon skeletons may differ in length; they could be straight, branched, or arranged in closed rings.
They can also include double bonds. Atoms of other elements may bond to the atoms of the carbon skeleton.
There are many different types of carbon isomers. Isomers are compounds that have the same molecular
formula but different structures which causes different chemical properties.
For example, butane and isobutane
have the same molecular formula, C
, but they each have a different skeleton and thus serve different
List and distinguish among the 3 types of isomers.
Isomers are compounds that have the same number of atoms of the same elements but different structures
and, thus, different chemical properties.
Structural Isomers –
have the same molecular formula, but the atoms
differ in their covalent arrangement. For example, butane and isobutane have the same molecular formula,
, but different skeletons.
Geometric isomers –
are compounds with the same covalent partnerships, but
they differ in the spatial arrangement molecules, or groups of atoms, attached to a a C = C double bond.
are molecules that are mirror images of each other. They differ in the spatial arrangement
around an asymmetric carbon. It is asymmetric because it is attached to four different atoms or groups of
